Mozilla Firefox postoji već gotovo dva desetljeća, s brojnim poboljšanjima stabilnosti i performansi. Međutim, još uvijek nije neuobičajeno naići na slučajeve sa zamrzavanjem preglednika odmah nakon pokretanja, tijekom rutinske upotrebe ili tijekom obavljanja određenih aktivnosti.

Ako imate problema s Firefoxom^(Firefox) koji ne reagira na vašem računalu ili Macu^(Mac) , prođite kroz popravke u nastavku da biste otklonili problem i riješili problem.

Ponovno pokrenite Firefox

Ako se Firefox upravo zamrznuo na vašem računalu ili Macu^(Mac) , pokušajte ga prisilno zatvoriti i ponovno pokrenuti. Za isključivanje preglednika na računalu desnom tipkom miša kliknite gumb Start i odaberite Upravitelj zadataka^{( Task Manager)} . Zatim odaberite Firefox s popisa otvorenih aplikacija i odaberite Završi zadatak^{(End task)} . Nakon toga ponovno pokrenite preglednik.

Otvorite Launchpad i odaberite Other > Activity Monitor ako koristite Mac. Zatim odaberite Firefox > Stop > Force-Quit i pokušajte ponovo pokrenuti Firefox .

Ponovno pokrenite računalo

Najbolje je ponovno pokrenuti računalo ako se Firefox nastavi smrzavati. U sustavu Windows^(Windows) samo otvorite izbornik Start^{(Start menu )} i odaberite Power > Restart .

Na Macu otvorite Appleov izbornik^{(Apple menu )} i odaberite Restart , ali poništite okvir pored Ponovno otvori prozore prilikom ponovne prijave^{(Reopen windows when logging back in)} prije nego što odaberete Restart ponovno u dijaloškom okviru za potvrdu.

Ponovno izradite bazu podataka o mjestima

Firefox pohranjuje vašu povijest pregledavanja i knjižne oznake u bazu podataka pod nazivom "Mjesta". Ponekad se može pokvariti i rezultirati neodgovaranjem web-preglednika. Da biste to isključili, morate prisiliti Firefox da ponovno stvori bazu podataka.

Odaberite ikonu izbornika Firefox^{(Firefox menu)} (gumb s tri naslagane linije u gornjem desnom kutu prozora) i odaberite Pomoć^{(Help )} > Više informacija o rješavanju problema^{(More troubleshooting information)} . Zatim, u odjeljku Osnove aplikacije^{(Application Basics)} , odaberite gumb Otvori mapu^{(Open Folder)} pored Mape profila^{(Profile Folder)} .

U prozoru File Explorer ili Finder koji se kasnije pojavi, otvorite svoju mapu Firefox profila i preimenujte donje datoteke dodavanjem .old na kraj naziva datoteke:

mjesta.sqlite^{(places.sqlite)}

mjesta.sqlite-journal^{(places.sqlite-journal)}

Ako Firefox potpuno ne reagira, možete izravno doći do mape profila putem File Explorera^{(File Explorer)} ili Findera^(Finder) .

Windows : Otvorite File Explorer , kopirajte i zalijepite sljedeću stazu u adresnu traku na vrhu prozora i pritisnite Enter :

%userprofile%\AppData\Roaming\Mozilla\Firefox\Profiles\

Mac : otvorite Finder i odaberite Go > Go to Folder . Zatim kopirajte i zalijepite sljedeću stazu i pritisnite Enter :

~/Library/Application Support/Firefox/Profiles

Ažurirajte da biste popravili Firefox

Mozilla izdaje česta ažuriranja za rješavanje poznatih problema u Firefoxu^(Firefox) . Kako biste provjerili je li preglednik ažuran, otvorite izbornik Firefoxa^{(Firefox menu )} i odaberite Postavke^(Settings) . Zatim se pod karticom Općenito^(General) pomaknite prema dolje do odjeljka Firefox ažuriranja^{( Firefox Updates)} i odaberite Provjeri ažuriranja^{(Check for updates)} .

Onemogući hardversko ubrzanje

Prema zadanim postavkama, Firefox koristi grafičku procesorsku jedinicu ( GPU ) na vašem računalu za poboljšanje funkcionalnosti i performansi web stranice. Međutim, ovisno o konfiguraciji vašeg računala ili Maca^(Mac) , to bi moglo imati suprotan učinak. Onemogućite hardversko ubrzanje^{(hardware acceleration)} i provjerite ima li to neku razliku.

Opet otvorite okno Postavke u ^{(Settings )}Firefoxu^{(Firefox )} i pomaknite se prema dolje do odjeljka Performanse . ^{(Performance )}Zatim poništite okvire pored Koristi preporučene postavke performansi^{(Use recommended performance settings)} i Koristi hardversko ubrzanje kada je dostupno^{( Use hardware acceleration when available)} .

Ako to pomaže, razmislite o ažuriranju upravljačkih programa za grafiku^{(updating the graphics drivers)} ili operativnog sustava (više o tome u nastavku) prije ponovnog ponovnog aktiviranja hardverskog ubrzanja.

Ažurirajte operativni sustav

Pokretanje ažurirane verzije operativnog sustava moglo bi pozitivno utjecati na rad Firefoxa^(Firefox) na vašem računalu. Za ažuriranje Microsoft Windows 10/11 otvorite aplikaciju Postavke^{(Settings )} i odaberite Windows Update . Zatim odaberite Provjeri ažuriranja^{(Check for updates)} > Preuzmi i instaliraj^{( Download and install)} .

Na Macu otvorite aplikaciju System Preferences i odaberite Software Update > Update Now . Ili otvorite Appleov izbornik^{(Apple menu)} i odaberite About This Mac > Software Update > Update Now .

Očistite predmemoriju Firefoxa

Zastarjela lokalna web predmemorija^{(obsolete local web cache)} još je jedan razlog za degradaciju performansi Firefoxa^{(performance degradation in Firefox)} . Izbrišite ga kako biste natjerali preglednik da dohvati ažurirane podatke web-mjesta.

Da biste to učinili, idite na Firefoxovo okno Postavke^{(Settings )} i prebacite se na karticu Privatnost i sigurnost^{(Privacy & Security)} . Zatim se pomaknite prema dolje do odjeljka Kolačići i podaci o web-mjestu , odaberite ^{( Cookies and Site Data )}Očisti podatke^{( Clear Data)} , označite okvire uz Kolačiće i podatke o web-mjestu^{( Cookies and Site Data)} i Predmemorirani web-sadržaj^{(Cached Web Content)} i odaberite Očisti^(Clear) .

Očistite predmemoriju pokretanja Firefoxa

Ako preglednik Firefox ima tendenciju zamrzavanja pri pokretanju, morate očistiti njegovu predmemoriju pokretanja. Započnite^(Start) otvaranjem izbornika Firefoxa^{(Firefox menu)} . Zatim idite na Pomoć^(Help) > Dodatne^{(More )} informacije o rješavanju problema^{(roubleshooting information)} i odaberite Očisti početnu predmemoriju^{(Clear startup cache)} .

Ako imate problema s posjetom gornjem zaslonu, morate osvježiti Firefox (više o tome u nastavku).

Izbrišite povijest preuzimanja Firefoxa

Zamrzava li se Firefox^{(Does Firefox)} samo dok izvanmrežno sprema datoteke? Opsežna povijest preuzimanja može uzrokovati to. Da biste ga izbrisali, otvorite izbornik Firefoxa^{(Firefox menu)} i odaberite Preuzimanja^(Downloads) > Obriši preuzimanja^{(Clear Downloads)} .

Promijenite mapu preuzimanja Firefoxa

Ako Firefox prestane odgovarati kad god pokrenete preuzimanje, pokušajte promijeniti mapu u koju preglednik prema zadanim postavkama sprema datoteke.

Otvorite okno Postavke^{(Settings )} , pomaknite se prema dolje do pododjeljka Preuzimanja i upotrijebite gumb ^{(Downloads )}Pregledaj^(Browse) za prebacivanje na drugu lokaciju. Izbjegavajte^(Avoid) prijenosne medije za najbolje rezultate.

Otvorite Firefox u načinu rada za rješavanje problema

Firefoxov način rješavanja problema^{(Troubleshoot Mode)} (ranije zvan Safe Mode ) učitava preglednik sa svim onemogućenim prilagodbama i dodacima. To vam pomaže utvrditi je li tema ili proširenje treće strane izvor problema.

Prvo zatvorite Firefox . Zatim^(Next) držite pritisnutu tipku Shift (PC) ili Option ( Mac ) i ponovno pokrenite preglednik. U skočnom prozoru koji se prikaže odaberite Otvori^{(Open )} da otvorite Firefox u načinu rada za rješavanje problema^{(Troubleshoot Mode)} .

Ako Firefox radi dobro u načinu rada za rješavanje problema^{(Troubleshoot Mode)} , otvorite izbornik Firefoxa^{(Firefox menu)} i odaberite Dodaci i teme^{( Add-ons and Themes)} . Zatim kopajte po kategorijama Proširenja^(Extensions) , Teme^{( Themes)} i Dodaci^{(Plugins )} i učinite sljedeće:

• Aktivirajte^(Activate) svaku stavku dok ne izolirate problematični dodatak ili temu.
• Uklonite dodatak ili temu.
• Ažurirajte^(Update) sva preostala proširenja i prilagodbe (odaberite ikonu u obliku zupčanika ispod svake kategorije i odaberite Provjeri ažuriranja^{(Check for updates)} ).

Osvježite Firefox

Ako ništa od gore navedenih rješenja ne pomogne, pokušajte osvježiti Firefox . To uklanja sve prilagodbe i proširenja i vraća preglednik na tvorničke postavke. Da biste to učinili, otvorite izbornik Firefoxa^{(Firefox menu )} i odaberite Pomoć^{(Help )} > Više informacija o rješavanju problema^{(More troubleshooting information)} . Zatim odaberite Osvježi Firefox^{( Refresh Firefox)} .

Alternativno, otvorite Firefox dok držite pritisnutu tipku Shift (PC) ili Option (Mac) i odaberite Osvježi Firefox^{( Refresh Firefox)} .

Postavite novi Firefox profil

Kako biste isključili probleme s oštećenim Firefox profilom, otvorite Firefox Profile Manager , odaberite Create Profile i postavite novi korisnički profil. Ako se Firefox nakon toga više ne smrzava ili ruši, možda ćete htjeti premjestiti podatke profila sa svog starog profila^{(migrate the profile data from your old profile)} .

Da biste pristupili Firefox Profile Manageru^{(Firefox Profile Manager)} , učinite sljedeće na svom računalu ili Macu^(Mac) . Ako je Firefox već pokrenut, zatvorite ga prije nego što počnete.

Windows : Desnom tipkom miša kliknite gumb Start , odaberite Pokreni^(Run) i izvršite sljedeće:

firefox.exe -P

Mac : Otvorite Launchpad i odaberite Ostalo^(Other) > Terminal . Zatim pokrenite sljedeću naredbu:

/Applications/Firefox.app/Contents/MacOS/firefox-bin -P

Ponovno instalirajte Firefox

Vjerojatno imate posla s oštećenom instalacijom Firefoxa^(Firefox) koju samo potpuna ponovna instalacija može popraviti. Da biste uklonili Firefox na računalu, desnom tipkom miša kliknite gumb Start , odaberite Aplikacije i značajke^{(Apps and Features)} i odaberite Firefox > Deinstaliraj^(Uninstall) . Samo povucite Firefox iz mape Applications u Trash ako koristite Mac.

Nakon deinstalacije Firefoxa^(Firefox) ponovno pokrenite računalo. Zatim preuzmite i instalirajte najnoviju verziju preglednika s Mozilla.com .

Nemojte popuštati zlonamjerni softver

Ako se Firefox povremeno ili cijelo vrijeme smrzava usprkos gore navedenim popravcima, možda imate posla sa zlonamjernim softverom. Koristite ove vrhunske antivirusne uslužne programe za PC^{(top antivirus utilities for the PC)} i Mac kako biste izvršili sveobuhvatno skeniranje računalnih virusa.

How to Fix Firefox Not Responding on PC and Mac

Mozilla Firefox has beеn around for almost two decadeѕ, with numerous stability and performance enhancements. However, it’s still not unсommon to encounter instances with the browser freezing right after launch, during routine use, or while performing specific аctivities.

If you’re having trouble with Firefox not responding on your PC or Mac, go through the fixes below to troubleshoot and resolve the issue.

Restart Firefox

If Firefox just froze on your PC or Mac, try force-quitting and relaunching it. To shut down the browser on PC, right-click the Start button and choose Task Manager. Then, choose Firefox from the list of open apps and select End task. Relaunch the browser after that.

Open the Launchpad and select Other > Activity Monitor if you use a Mac. Then, select Firefox > Stop > Force-Quit and attempt to start Firefox again.

Restart Your Computer

It’s best to restart your computer if Firefox continues to freeze. In Windows, just open the Start menu and select Power > Restart.

On the Mac, open the Apple menu and select Restart, but clear the box next to Reopen windows when logging back in before selecting Restart again on the confirmation dialog.

Recreate the Places Database

Firefox stores your browsing history and bookmarks in a database called “Places.” Sometimes, it can corrupt and result in the web browser not responding. To rule that out, you must force Firefox to recreate the database.

Select the Firefox menu icon (the button with three stacked lines at the top right corner of the window) and choose Help > More troubleshooting information. Then, under the Application Basics section, select the Open Folder button next to Profile Folder.

On the File Explorer or Finder window that subsequently shows up, open your Firefox profile folder and rename the files below by adding .old to the end of the file name:

places.sqlite

places.sqlite-journal

If Firefox is completely unresponsive, you can directly get to the profile folder via File Explorer or Finder.

Windows: Open File Explorer, copy and paste the following path into the address bar at the top of the window, and press Enter:

%userprofile%\AppData\Roaming\Mozilla\Firefox\Profiles\

Mac: Open Finder and select Go > Go to Folder. Then, copy and paste the following path and press Enter:

~/Library/Application Support/Firefox/Profiles

Update to Fix Firefox

Mozilla releases frequent updates to address known issues in Firefox. To check if the browser is up-to-date, open the Firefox menu and select Settings. Then, under the General tab, scroll down to the Firefox Updates section and choose Check for updates.

Disable Hardware Acceleration

By default, Firefox takes advantage of the graphics processing unit (GPU) on your computer to improve web page functionality and performance. However, depending on your PC or Mac configuration, that could have the opposite effect. Disable hardware acceleration and check if that makes a difference.

Again, open the Settings pane in Firefox and scroll down to the Performance section. Then, uncheck the boxes next to Use recommended performance settings and Use hardware acceleration when available.

If that helps, consider updating the graphics drivers or the operating system (more on that next) before reactivating hardware acceleration again.

Update the Operating System

Running an up-to-date version of the operating system could positively impact how Firefox runs on your computer. To update Microsoft Windows 10/11, open the Settings app and select Windows Update. Then, choose Check for updates > Download and install.

On the Mac, open the System Preferences app and select Software Update > Update Now. Or, open the Apple menu and choose About This Mac > Software Update > Update Now.

Clear the Firefox Cache

An obsolete local web cache is another reason for performance degradation in Firefox. Delete it to force the browser to fetch up-to-date site data.

To do that, go to Firefox’s Settings pane and switch to the Privacy & Security tab. Then, scroll down to the Cookies and Site Data section, select Clear Data, mark the boxes next to Cookies and Site Data and Cached Web Content, and select Clear.

Clear Firefox’s Startup Cache

If the Firefox browser tends to freeze at launch, you must clear its startup cache. Start by opening the Firefox menu. Next, go to Help > More troubleshooting information and select Clear startup cache.

If you have trouble visiting the screen above, you must refresh Firefox (more on that further below).

Clear Firefox’s Download History

Does Firefox only freeze while saving files offline? An extensive download history can cause that. To clear it, open the Firefox menu and select Downloads > Clear Downloads.

Change the Firefox Downloads Folder

If Firefox stops responding whenever you initiate a download, try changing the folder where the browser saves files by default.

Open the Settings pane, scroll down to the Downloads sub-section, and use the Browse button to switch to a different location. Avoid removable media for best results.

Open Firefox in Troubleshoot Mode

Firefox’s Troubleshoot Mode (formerly called Safe Mode) loads the browser with all customizations and add-ons disabled. That helps you determine if a third-party theme or extension is the source of the issue.

First, close Firefox. Next, hold down the Shift (PC) or Option (Mac) key and relaunch the browser. On the pop-up window that shows, select Open to open Firefox in Troubleshoot Mode.

If Firefox works OK in Troubleshoot Mode, open the Firefox menu and select Add-ons and Themes. Then, dig into the Extensions, Themes, and Plugins categories and perform the following:

• Activate each item until you isolate the problematic add-on or theme.
• Remove the add-on or theme.
• Update all remaining extensions and customizations (select the gear-shaped icon under each category and select Check for updates).

Refresh Firefox

If none of the fixes above help, try refreshing Firefox. That removes all customizations and extensions and resets the browser to factory defaults. To do that, open the Firefox menu and select Help > More troubleshooting information. Then, choose Refresh Firefox.

Alternatively, open Firefox while holding down the Shift (PC) or Option (Mac)keys and select Refresh Firefox.

Set Up a New Firefox Profile

To rule out issues with a corrupt Firefox profile, open the Firefox Profile Manager, select Create Profile, and set up a new user profile. If Firefox no longer freezes or crashes after that, you may want to migrate the profile data from your old profile.

To access the Firefox Profile Manager, perform the following on your PC or Mac. If Firefox is already running, close it before you begin.

Windows: Right-click the Start button, select Run, and execute the following:

firefox.exe -P

Mac: Open the Launchpad and select Other > Terminal. Then, run the following command:

/Applications/Firefox.app/Contents/MacOS/firefox-bin -P

Reinstall Firefox

It’s likely you’re dealing with a corrupt Firefox installation that only a complete reinstallation can fix. To remove Firefox on the PC, right-click the Start button, choose Apps and Features and select Firefox > Uninstall. Just drag Firefox from the Applications folder into the Trash if you use a Mac.

After uninstalling Firefox, restart your computer. Then, download and install the latest version of the browser from Mozilla.com.

Don’t Discount Malware

If Firefox freezes occasionally or all the time despite performing the above fixes, you may be dealing with a malware infestation. Use these top antivirus utilities for the PC and Mac to perform a comprehensive scan for computer viruses.
